fix(node): normalize blob values before schema inference

Give every blob value the full { data, uri } shape before inference so rows
mixing bytes, URIs, and partial structs infer one struct type. Also wrap
blob validation errors with the field and row, regenerate the TypeScript
docs, and cover URL handling end to end.

+type BlobInput:

+  | object
+  | null
+  | undefined;
+```
+
+A value accepted for a `lance.blob.v2` column (see [blob](../functions/blob.md)).
+
+Either inline bytes, a URI pointing at external bytes, or a struct that sets
+exactly one of `data` or `uri`. `null` and `undefined` write a null blob.
+
+## Example
+
+```ts
+import { pathToFileURL } from "node:url";
+import type { BlobInput } from "@lancedb/lancedb";
+
+const rows: { id: bigint; image: BlobInput }[] = [

+  { id: 2n, image: pathToFileURL("/data/cat.png") },
+  { id: 3n, image: { data: new Blob(["hello"]) } },
